My invention relates to dump door operating iili-iciianisms and thehire.

It is an .object of my invention to provide. novel means for rotatingand operating` dump door operating shafts .in a safev and convenientmanner "from a location remote from the shaft.

rtnother object of my invention is to pro` vide in a shaft adapted to bereciprocated by rotation thereof means'whereby the exertion of turningforce thereon will also operate to` specification, Figure 1 is a sideelevational.

view of a portion of a car showing so much of the car and door mechanismas embodies my improvements. Figure 2 is a transverse,

fi ctional view taken through a` portion of the car at `the doormechanism and taken on a line corresponding substantially to a line 2*.2of Fig. 1'. Figure Bis a transverse sectional view, taken through thecar and on a line correspondingsubstantially to a line" ri-o ofFigure 1. Figure 4 is a perspective view of that portion of theIfriimework adl' jacent the door operating mechanism. Figure is aperspective view of the reciprocating element. Figure 6 is a viewsimilar to Figure 3 but showing the shaft actuating means in a differentoperating re* lation to the shaft. Figure 7 is a view of the shaftactuatingmechanism as shown in operative engagement with the shaft atthe time of the end of the door closing operation, with the shaftbeneath the door. Figure 8 is a view with the shaft in the same.position as Figure 'l but illustrating the parts of theinechanismpositioned to commence the release operation of the mechanism. Figure 9is a vertical elevationalview showing a portion of the end of a car withmy improved construction embodied therein, the construction herein shownbeing an alternate arrangement applicable to cars wherein vthe dooroperating shafts are extended beyond the end sills of the car. Figure 10is a side longitudinal elevational view of the car showing so much ofthe car as will illustrate the parts shown in F ig. 9 inl side view.

in said' drawings and referring lirst toV the construction illustratedinFigs. 1 to inclusive, the invention is shown as applied to a gondolatype of car provided with a` longitudinalside sill 10 and transversebeamorbolster 11 secured thereto. One of the dump doors 12, of which theouter portion only thereof is shown in dotted lines, is in `dicatedV inFig. 2 and includes a suitable framework 13 to which are securedbrackets 14 each provided with a serrated face 15. Connection' is madebetween each door and a longitudinally extending `shaft 16by means offlexible elements 17 shown conventionally in Fig. 2, of which there arepreferably two associated with each door. Onv each shaftoppositeeachbraclret le and coope`rable with the serrated faces areserratedwheels 18 rigidly secured to the shaft 16. The door shaft ltissupported in bearing plates 19 secured to the transverse beams 11. Eachof the bearing plates, as shown, is formed with an elongated slot Q0,having a depressed bearing portion 21 at the outer end thereof.

lVhile the drawings show onlyV a portionof the car, it will beunderstood that the typeof car referredtoincludes a longitudinal centersill construction',l havingthe crossbeams 11 extending outwardly fromthe center sills to the side sills of the car` and connected thereto,land the doors '.12 are preferablyI hinged to the center sill anddisposed between the respective crossbearers.

1n the particular construction illustrated in Figs. 1 to 8 inclusive,the mechanism associated with the shaftl consists of devices forsecuring the shaft against unintentional reverse rotation thereof,during the raisingl 'operation and for positively locking the shaft insupporting' position beneath the doors, and is designated broadly by thereference characterA.. There is also a separate mechanism'for inducingrotary njioveinenty of the shaft, saidV mechanism being designatedbroadly by tlie'refeie'nce character B. in this general type of;mechanism, as the shaft 16 is turned in a closingdirection, the flexibleelements 17 wind on the shaftthus lifting the doors until the'latter'are almost in closed position, at which time further windL ing'of themembers 17 on the shaft pull the same inwardly along the bearing slotsunt-il the serrated wheels 18 engage with the rounded serrated faces 15of the brackets and thereafter the shaft is moved under'the doors, thusforcing the latter to fully closed position and also holding them closedwith the load transferred to the shafts.

The mechanism A consists of a Creeper formed of a plurality of platesections 22-22 mounted on the shaft and movable in unison therewith,said creeper having an arm 23 outstanding therefrom, formed by bringingthe respective platev sections 22-22 together and uniting the same by arivet 24, a weight pawl 25 pivotally mounted on the Creeper and adaptedto have cio-operating engagement with a ratchet Wheel 26 rigidly securedto the shaft, and a cam 27 which is pivotally mounted on the Creeper andadapted to lock the pawl 25 relatively to the ratchet wheel 26.

The arm 23 of the creeper is adapted to slide within a perforation 28formed in a bracket guide 29. Said bracket kguide 29 extends outwardlyfrom the cross member 11 and isfurthcr braced laterally by a; gussetmember 30 extending outwardly from the outstanding flange 31 of thecross member 11.

The mechanism B for imparting rotary motion to the shaft consists of areciprocartory element 32 having a pair of spaced pawls 33-33 pivotallymounted thereon and co-operable with a ratchet wheel 34 which is rigidlymounted on the shaft. Said reciprocating Velement is preferably disposedbeneath the shaft in alinement with the ratchet 34 and supported on theopposite sides-of the shaft, one of said supports includes a lever 35which is pivotally mounted at 36 on a fulcrum bracket 37 carried by theside sill 10 of the Car, and the other su port preferably consists `of afixed brac ret on the framework of the car on which the said element isadapted to slide, and in the'present embodiment of my invention thefixed guide 29 which forms the guide for the member A is formed with anadditional perforation 38 through which one end of the said elementV 32is extended. Said reciprocatory el-ement V32 is preferably formed ofrtwo bar sections 39-39 united by rivets 40-40 and having a portionthereof intermediate said rivets separated to form a space 41 betweensaid sec* tions. The outer end of the element 32 is deflected downwardlyat 42 andL the end thereof isdisposed between spaced walls 43-43 formedintegrally :with the lever member 35, and a pivot 44 operativelyconnects the said members. The lever member 35 is provided below thepivot 44 with a socket portion 45 adapted to receive a removableactuating tool whereby operation of the mechanism may be effected.A

The fulcrum bracket 37 is provided with angularly related wallsindicated at 46 and 47 and which are secured to the web and flange ofthe channel side sill member 10 by rivets as indicated at 46 and 47respectively, and a plurality of walls 48,748 depend from said angularlyrelated walls, said walls 48-48 are Vspaced from each other suicientlyto receive pivotal end 'of the lever rection by means of a removable bar53,

thereby moving reciprocatory element 32 and therefore the pawl member 33upwardly and away from the sideof the car until the parts assume theposition illustrated in Fig. 6, the pawl 33 exerting aywedging actionduring such movement between the element 32 and the engaged tooth 49 ofthecooperating ratchet wheel 34.l The operation is repeated untilsuchntime as the flexible element is wound upon the shaft and the doorsare lifted to a fully closed position and the shaft has travelledinwardly to a supporting position beneath the door, being drawn inwardlythereunder by reason of the flexible element winding on the shaft, theparts then assuming the position as illustrated in Fig. 7

The commencement of the door opening operation is illustrated in Fig. 8,the innermost pawl 33 being illustrated in engagement with the ratchetwheel 34 while the companion pawl used in the raising opera- Ytion hangsin idle position. The length of the vpawls and the. extent ofreciprocation of the element 32 are adjusted to enableoperatingengagement between the respective pawls and ratchet wheelthroughout the entire movement of the shaft. The pawls 33 are adapted tobe manually positioned into engagement with the ratchet wheel 34 on eachreciprocation ofthe element 32 there by assuring complete safety to theoperator as the pawls drop of their own weight to a vertically dependingposition below the ratchet wheel and therefore as the shaft travelsoutwardly during the releasing operation of the' doors,-the shafttravels away from and independently of the reciprocating' element 32 andcooperating pawls 33.

In Figs. 9'and 10 the invention is shown as applied to a car wherein themechanism is located outwardly of the end sill, the shaft being extendedthrough the end sill of the Car. In Figures 9 andlO, 110 indicates theend wall of the car, 111 the end sill, 112

the side sill of the car and 113 a horizontal gusset connecting the endsill and side sill. Mounted on the end sill is a slotted bracket 11a,said bracket being,` formed with angular walls 115 and 11G respectivelysecuredto the side sill 112 of the car and to the horizontal gussets113, said braclret also being provided with a plurality of dependingwalls 117-117 disposed in spaced relation and braced to the main body ofthe bracket by horizontal flange 118 and vertical flanges 119 and 120. Abodily movable door operating shaft 121 is extended through the slot inthe bracket 1111, and a ratchet wheel 122 is fixedly mounted on the endthereof. A creeper 123 is mounted on the shaft and formed with` walls12a` either side of the ratchet whe-el 122. A lockingpawl 125 andco-operating` locking; c m12()I are pivotally mounted between said walls121-12Ll said members 125 and 126 being disposed above the ratchetwheel. The outer end of the creeper is extended within a perforation12?1 formed in a bracket guide 128 carried by the end sill of the car.Pivotally mounted between the dependinggl walls 117-117 of the bracket114e is a lever member 129 formed with a soclret portion 130, said leveris pivotally connected with a reciprocatingI element 131 at 132. Thesaid element 131 .is supported at its opposite end and adapted to havesliding` n'ioveinent in a perforation 133 formed in said guide 128.Opposit'ely disposed pawls 1341, mounted on the reciprocating` eement1.31 are adapted to have co-operating engagement with the ratchet wheel122 to rotate the shaft.
